The arrival of the cardinal, Morone, whom the Pope had appointed to attend the Diet as his nuncio, completed their conviction, and left them no room to doubt that some dangerous machination was forming against the peace or safety of the Protestant Church. Julius, elated with the unexpected return of the English nation from apostasy, began to flatter himself that, the spirit of mutiny and revolt having now spent its force, the happy period was come when the Church might resume its ancient authority, and be obeyed by the people with the same tame submission as formerly. Full of these hopes, he had sent Morone to Augsburg with instructions to employ his eloquence to excite the Germans to imitate the laudable example of the English, and his political address in order to prevent any decree of the Diet to the detriment of the Catholic faith. But Julius died, and as soon as Morone heard of this he set out abruptly from Augsburg, where he had resided only a few days, that he might be present at the election of the new pontiff.

One cause of their suspicions and fears being thus removed, the Protestants soon became sensible that their conjectures concerning Ferdinand's intentions, however specious, were ill-founded, and that he had no thoughts of violating the articles favorable to them in the Treaty of Passau. Charles, from the time that Maurice had defeated all his schemes in the empire, and overturned the great system of religious and civil despotism which he had almost established there, gave little attention to the internal government of Germany, and permitted his brother to pursue whatever measures he judged most salutary and expedient. Ferdinand, less ambitious and enterprising than the Emperor, instead of resuming a plan which he, with power and resources so far superior, had failed of accomplishing, endeavored to attach the princes of the empire to his family by an administration uniformly moderate and equitable. To this he gave, at present, particular attention, because his situation at this juncture rendered it necessary to court their favor and support with more than usual assiduity.

Charles had again resumed his favorite project of acquiring the imperial crown for his son Philip, the prosecution of which, the reception it had met with when first proposed had obliged him to suspend, but had not induced him to relinquish. This led him warmly to renew his request to his brother, that he would accept of some compensation for his prior right of succession, and sacrifice that to the grandeur of the house of Austria. Ferdinand, who was as little disposed as formerly to give such an extraordinary proof of self-denial, being sensible that, in order to defeat this scheme, not only the most inflexible firmness on his part, but a vigorous declaration from the princes of the empire in behalf of his title, were requisite, was willing to purchase their favor by gratifying them in every point that they deemed interesting or essential.

At the same time he stood in need of immediate and extraordinary aid from the Germanic body, as the Turks, after having wrested from him a great part of his Hungarian territories, were ready to attack the provinces still subject to his authority with a formidable army, against which he could bring no equal force into the field. For this aid from Germany he could not hope, if the internal peace of the empire were not established on a foundation solid in itself, and which should appear, even to the Protestants, so secure and so permanent as might not only allow them to engage in a distant war with safety, but might encourage them to act in it with vigor.

A step taken by the Protestants themselves, a short time after the opening of the Diet, rendered him still more cautious of giving them any new cause of offence. As soon as the publication of Ferdinand's speech awakened the fears and suspicions which have been mentioned, the electors of Saxony and Brandenburg, together with the Landgrave of Hesse, met at Naumburg, and, confirming the ancient treaty of confraternity which had long united their families, they added to it a new article, by which the contracting parties bound themselves to adhere to the Confession of Augsburg, and to maintain the doctrine which it contained in their respective dominions.

Ferdinand, influenced by all these considerations, employed his utmost address in conducting the deliberations of the Diet, so as not to excite the jealousy of a party on whose friendship he depended, and whose enmity, as they had not only taken the alarm, but had begun to prepare for their defence, he had so much reason to dread. The members of the Diet readily agreed to Ferdinand's proposal of taking the state of religion into consideration previous to any other business. But, soon as they entered upon it, both parties discovered all the zeal and animosity which a subject so interesting naturally engenders, and which the rancor of controversy, together with the violence of civil war, had inflamed to the highest pitch.

The Protestants contended that the security which they claimed in consequence of the Treaty of Passau should extend, without limitation, to all who had hitherto embraced the doctrine of Luther, or who should thereafter embrace it. The Catholics, having first of all asserted the Pope's right, as the supreme and final judge with respect to all articles of faith, declared that though, on account of the present situation of the empire, and for the sake of peace, they were willing to confirm the toleration granted by the Treaty of Passau to such as had already adopted the new opinions, they must insist that this indulgence should not be extended either to those cities which had conformed to the "interim," or to such ecclesiastics as should for the future apostatize from the Church of Rome. It was no easy matter to reconcile such opposite pretensions, which were supported, on each side, by the most elaborate arguments, and the greatest acrimony of expression, that the abilities or zeal of theologians long exercised in disputation could suggest. Ferdinand, however, by his address and perseverance; by softening some things on each side; by putting a favorable meaning upon others; by representing incessantly the necessity as well as the advantages of concord; and by threatening, on some occasions, when all other considerations were disregarded, to dissolve the Diet, brought them at length to a conclusion in which they all agreed.

Conformably to this, a recess was framed, approved of, and published with the usual formalities. The following are the chief articles which it contained: That such princes and cities as have declared their approbation of the Confession of Augsburg shall be permitted to profess the doctrine and exercise the worship which it authorizes, without interruption or molestation from the Emperor, the King of the Romans, or any power or person whatsoever; that the Protestants, on their part, shall give no disquiet to the princes and states who adhere to the tenets and rites of the Church of Rome; that, for the future, no attempt shall be made toward terminating religious differences but by the gentle and pacific methods of persuasion and conference; that the Popish ecclesiastics shall claim no spiritual jurisdiction in such states as receive the Confession of Augsburg; that such as had seized the benefices or revenues of the Church, previous to the Treaty of Passau, shall retain possession of them, and be liable to no persecution in the imperial chamber on that account; that the supreme civil power in every state shall have right to establish what form of doctrine and worship it shall deem proper, and, if any of its subjects refuse to conform to these, shall permit them to remove with all their effects whithersoever they shall please; that if any prelate or ecclesiastic shall hereafter abandon the Romish religion, he shall instantly relinquish his diocese or benefice, and it shall be lawful for those in whom the right of nomination is vested to proceed immediately to an election, as if the office were vacant by death or translation, and to appoint a successor of undoubted attachment to the ancient system.

Such are the capital articles in this famous recess, which is the basis of religious peace in Germany, and the bond of union among its various states, the sentiments of which are so extremely different with respect to points the most interesting as well as important. In our age and nation, to which the idea of toleration is familiar, and its beneficial effects well known, it may seem strange that a method of terminating their dissensions, so suitable to the mild and charitable spirit of the Christian religion, did not sooner occur to the contending parties. But this expedient, however salutary, was so repugnant to the sentiments and practice of Christians during many ages that it did not lie obvious to discovery. Among the ancient heathens, all whose deities were local and tutelary, diversity of sentiments concerning the object or rites of religious worship seems to have been no source of animosity, because the acknowledging veneration to be due to any one god did not imply denial of the existence or the power of any other god; nor were the modes and rites of worship established in one country incompatible with those which other nations approved of and observed. Thus the errors in their system of theology were of such a nature as to be productive of concord; and, notwithstanding the amazing number of their deities, as well as the infinite variety of their ceremonies, a sociable and tolerating spirit subsisted almost universally in the Pagan world.

But when the Christian revelation declared one Supreme Being to be the sole object of religious veneration, and prescribed the form of worship most acceptable to him, whoever admitted the truth of it held, of consequence, every other system of religion, as a deviation from what was established by divine authority, to be false and impious. Hence arose the zeal of the first converts to the Christian faith in propagating its doctrines, and the ardor with which they labored to overturn every other form of worship. They employed, however, for this purpose no methods but such as suited the nature of religion. By the force of powerful arguments, they convinced the understandings of men; by the charms of superior virtue, they allured and captivated their hearts. At length the civil power declared in favor of Christianity; and though numbers, imitating the example of their superiors, crowded into the church, many still adhered to their ancient superstitions. Enraged at their obstinacy, the ministers of religion, whose zeal was still unabated, though their sanctity and virtue were much diminished, forgot so far the nature of their own mission, and of the arguments which they ought to have employed, that they armed the imperial power against these unhappy men, and, as they could not persuade, they tried to compel them to believe.
